Some shops have a way of testing flow to see if it's clogged...

start the car and put your hands in front of the exhaust tips for a few seconds

then smell them. should be a nasty, rotten egg smell if they are clogged.

thats what mine did anyway. and if your not sure, gut it anyway!

A muffler shop will do a heat test on it to see if the cat is bad.
